SPECIFICATION forming part of lLetters Patent No. 347,329, dated August17,] 886.

y Application filed January 13, 1886. Serial No.18SAG-1. (No model.) l

' Grand Rapids, in the county of Kent and State of Michigan, haveinvented a new anduseful Improvement in Machines for Applying Glue toVeneers; and I do hereby declare that the following is a full, clear,and exact description of the same.

AMy invention is an improved machine for applying glue to veneers.

The object of the invention is to provide a simple and eficientapparatus for the purpose, combined with mechanism i'or adj ustingl theapparatus to different thicknesses of the material to be coated. Y

In the accompanying drawings, 'Figure l represents an end view of theapparatus, with the lower p'art or tank in cross-section. Fig. 2 is aside elevation, and Fig.3 is a plan view, of the apparatus.

The apparatus has a base consisting of a tank'or reservoir, B, for theglue, and under this Va steam-heating chamber, A, with pipeconnections ab and drain-pipe I). The gluereservoir is open above and has adrain-passage, c. In each end of the reservoir is a frame, C, havingarms c, extending laterally, and in this frame are the bearings for thejournals of the lower roller, M. Uprights C C are connected to theframes C by means of rods K K', which also connect the frames of one endto those of the other,-and th`ese are connected ateach end bycross-pieces J. The cross-pieces J are connected to the uprights bymeansof the rods K K, which also run from end to end of the apparatus, andconnect the entire end frames with each other.

Between the uprights G C', and extending across from side to side, areyokes D D. The ends embrace the uprights and slide thereon. In theseyokes are the bearings for the journals of thenpper roller, M. Rods E E,adapted to be turned by hand, are threaded through these yokes, and thelower ends of these rods rest on the arms c of the lower frames. Therods serve to separate the rollers and determine their distance fromeach other. Other rods, F, one at each end, are threaded in thecross-pieces of the upper frames, and have collarsGbelow their threadedbearings, and coiled springs, which the collars press upon the yokes.Ihus the springs hold down the yokes, and therewith the upper rollersare warm by the heat imparted by the steam below it. lIhelower rollertakes up the glue and applies it directly to the under side of theveneer passed through between the rollers. The veneers are usuallysupplied to the rollers in pieces,and, as the rollers run constantly,the lower roller applies the glue to the upper in the intervals betweenthe application ot successive pieces of veneer. In case it be desiredvto coat veneers of considerable length from rolls, a second gluetank canbe placed above the upper roller and glue applied therefrom to saidroller.

I am aware that it is not new to pass veneers and fabrics betweenrollers to supply glue and other coatings, and also that it is not newto provide a fixed distributing'- roller and a vert cally-adjustableroller above the same for this purpose.

I claim as my invention- 1. In a machine forapplying glue-to veneers andlike forms, in combination, a glue-reservoir, a roller in fixed bearingstherein, an upper roller, rods threaded in the bearings of the upperroller, whereby it may be adjusted in relation to the lower roller, saidrods resting at their lower ends upon the frame, and pressure devicesfor the bearings of said'upper roller, substantially as described.

2. In combination with the reservoir, the frames C G, and lower roller,the uprights C C', connected thereto and to each other, the yokes D D,supporting the upper roller, the threaded rods E, for adjusting theyokes, and the threaded rods F F, seated in the frame with springs forapplying pressure to the yokes upon the same, substantially asdescribed.

In testimony whereof I have signed my name to this speciiicationinthepresence of two subscribing witnesses.
